AI Technical Summary

Benefits of technology

This approach enables the production of blocks with customizable lengths, reducing material waste and associated costs by allowing for precise cutting of blocks to meet specific panel requirements without generating excess material.

Problems solved by technology

When, as it is often the case, the height of the panels does not correspond precisely to the length of a standardised block, a corresponding portion of the block must be cut, consequently producing material waste, and as a result waste or problems and costs for disposal.

Embodiment Construction

[0019]The present process for producing blocks of material, which for better understanding is described with reference to the apparatus illustrated in FIGS. 3 to 6, involves the production of a working block 51, consisting of said material, from which at least one corresponding predetermined block 53 is obtained.

[0020]In particular, the material is an insulating material, especially a plastic material and, preferably, an expanded material, such as expanded polystyrene.

[0021]In turn, the predetermined block is, in particular, suitable for constituting a corresponding panel for producing a structure, in particular a building.

[0022]Advantageously, according to the process, the working block 51 is produced by means of a plurality of separate forming steps.

[0023]Advantageously, the working block 51 is produced by means of a plurality of successive steps, in particular, moulding, for forming the block.

[0024]In particular, as illustrated, the working block 51 has the shape of a longitudina...

Abstract

In a process and a device for producing blocks of expanded polystyrene, a loose mass (7) of polystyrene spheres is expanded in a mold (2-3), where a rear surface (9) of the polystyrene block (8) previously produced delimits the mold forming chamber. Therefore, through adherence the newly formed block (7-8) is joined to the rear end (9) of the block previously formed, and the block (8) made in this way is fed forward until it forms the rear end (9) for another newly expanded block (8), and so on to produce a sort of continuous block (8), which can be formed for cutting to any desired size, without producing any waste.

Description

TECHNICAL FIELD[0001]The present invention relates to a process and an apparatus for producing blocks of material.[0002]In particular, said material consists of an insulating material, especially a plastic material, preferably an expanded material, such as expanded polystyrene.[0003]The predetermined block is suitable for constituting a corresponding panel for producing a structure, in particular a building.BACKGROUND ART[0004]Expanded polystyrene is usually produced in blocks having the shape of a parallelepiped and is supplied in that form to users, who use cutting operations to obtain slabs or other three-dimensional shapes from it, necessary for their specific requirements.[0005]Such blocks are fully formed, in a single operation, in moulds, fully perforated, into which a suitable quantity of loose polystyrene spheres is poured, which is then struck, substantially on all sides, by a flow of steam that penetrates from the walls of the mould in which there are openings, causing th...
